To all whom it may concern:

Be it known that I ABLE F. HART, a citizen of the United States,residing at Hickory, in the county of Catawba and State of NorthCarolina, have invented a new and useful Track-Tamping Implement; ofwhich the following is a specification.

This invention has relation to track tamping implements and it consistsin the novel construction and arrangement of its parts as hereinaftershown and described.

The object of the invention is to provide an implement which may bereadily used for the purpose of tamping and packing ballast under thecross ties of a railroad track and means is provided for fixing theimplement with relation to the track and the tie during such operation.

The implement consists primarily of a wheel mounted axle which in turnsupports Clamp members are hingedly attached to the lower ends of saidstandards and are adapted to be forced against the sides of the trackrails and under the heads thereof for the purpose of fixing theimplement with relation to the said rail. Arms are journaled at theirinner ends to the axle and bars are carried by the outer ends of saidarms. Sleeves are adjustably mounted upon said bars and tamping bits areadjustably positioned in the'sleeves. Operating levers having segmentalgear ends are adapted to operate against the opposite edges of the rackstandards and when depressed bear against said bars for the purpose offorcing the same and the bits carried thereby in downward directions.Each lever is provided with a pawl which engages an aperture provided inthe bar at a point immediately below the lever. Said awls aflord meansfor raising the bars and t e bits as the levers are swung up.

- the points of intersection of the ties and rail.

'Other advantages incident to the-arrangement of the parts of thetamping implement will appear as the several parts of the implement aredescribed in detail.

is mounted upon the a transverse sectionalview of the implement cut onthe line 1, 1 of Fig. 2. Fig. 2 is a top plan view of the implement.Fig. 3 is a side elevation of a bit used upon the implement for tampingunder the intersection of a rail and tie, and Fig. 4 is a plan view ofthe intermediate portion of a longitudinally extensible member forholding the clamps against the rails.

The implement consists of the axle 1 which wheels 2, 2. The rackstandards 3 are mounted at the end portions of the axle and are rovidedat their edges with the teeth 4. T e clamp members 5 are hingedlyattached to the lower ends of" the standards 3 and are adapted to beforced into contact with the inner sides of the track rails 6andbelow'the heads thereof by means of the longitudinally extensiblecross bar 7. As indicated in Fi 4 the said bar 7 may be composed of toescoping sections which are moved longitudinally with relation to eachother by means of the lever'and cam mechanism 8. Thus, it will be seenthat when the bar 7 is extended against the inner side of the clampmembers 5 the said members are forced against the sides of the rails '6and. the tampingimplement is fixed with relation to the rails. The arms9 are journaled at the end ortions of the axle 1 and the transverse ydisposed bars 10 are mounted in the said arms and lie upon oppositesides of the axle 1. The sleeves 11 are adjustably mounted u on the bars10 and the bits 12 are adjusta ly mounted in the said sleeves 1-1. Thelevers 13 are provided at their ends with the gear segments 14. adaptedto adjustably enga Said segments are e the teeth 4 of the standards 3and the sai levers bear laterally against the bars 10 at the oints 15.Each lever is provided with a paw 16 which is adapted to enter a recess17 provided in the bar 15. Thus it will be seen that when the gearsegments 14 of the levers 13 are engaged with the teeth 4 of thestandards 3 and the outer ends of the said levers are reciprocatedvertically as the lever moves down it bears upon the upper side of thebar 10 which together with the bits 12 are correspondin ly depressed.Thus, the lower ends of the iit 12 force the ballast material under thetie 18. When'the outer end of the lever 13 isswung up thepawl 16 whichisin engagement with the bar 10 carries the said bar and the attachedbits 12 up. Thus, the bar and bits In the accompanying drawing: Figure 1is l are reciprocated by the movement of the levers. In order toregulate the extent of the thrust of the bits 12 the gear segments 14may be so mounted upon the teeth 4 of the standards 3 as to cause thesaid bits to have major or minor thrust or movement under the tie 18.

In the present invention provision is male for tamping and packing theballast material under a tie at the point of intersect on of the trackrail. The means for accomplishing this mode of tamping consists of thebits 19 which are connected by means of the ball and socketmechanismwith the bars 10. Said bits 19 are located adjacent the track rails 6.The clips 21 are slidably mounted upon the track rails 6 and the guides22 are pivotally connected with the said clips the bits 19 pass throughthe orifices 23 provided in the said guides 22. The shape of the bits 19along the portions thereof which operate in the orifices 23 of theguides 22 issuch as to cause the lower ends of the bits 19 to moveobliquely with relation to the track rails 6 as the bars 10 arereciprocated. In order to accom lish this movement the said bits 19 turnaxiaily at the joints 20 and consequently they work the ballast materialunder the tie 18 and pack the same immediately beneath the track rails6. It is essential to pack the ballast material at these points for theyare directly beneath the weight of rollin stock standing upon or passingover the rails 6.

It will be observed that the gear segments 14 may be engaged with theupper or lower teeth 4 of the rack standards 3 and when the segments 14are engaged with the lower teeth of the said rack standards the bits 12may be forced to operate at a greater depth below the surface of thetrack bed than when the said segments 14 are in mesh with the u perteeth of the said standards. Thus, provision is made for so positioningthe parts with relation to each other as to cause the said bits tooperate near or remote from the surface of the track bed.
